Clinical Studies YTE Research
YTE increases sexual desire in healthy middle-aged men.
The study was a three-week, double-blind study, conducted to measure sexual health.
The participants were sixteen healthy Norwegian and Swedish men, ages forty-seven to sixty. Half the participants received Youth Tissue Extract, and the rest received a placebo. In the second part of the study, the treatments were reversed. The patients rated their feelings of sexual desire every week using a visual analog scale that ranged from a score of 0 (no change) to 10 (very pronounced change). The results showed that sexual desire increased significantly more when the men took YTE than when they took the placebo.
Most of the men experienced increases in sexual arousal as early as two weeks after starting treatment with YTE. None of the men reported any side effects. In addition, sexual desire typically remained elevated for a short time even after the men switched from YTE to placebo.
YTE increases sexual satisfaction in adult patients taking antidepressants.
A Swedish professor, Dr. Kjell Tornblum, conducted a study at the University of Colorado in Denver involving five men and three women. The participants—men ages twenty-nine to sixty-seven and women ages twenty-six to thirty-nine—were experiencing decreased sexual satisfaction after taking antidepressants for a period of three weeks or more. The duration of the study was six weeks. For the first three weeks, the participants took a daily dose of 2.8 g of YTE. After two weeks, their intensity and frequency of sexual satisfaction increased (on a subjective scale from 0 to 9 rating the intensity of orgasm). Over the course of the first three weeks, the increase nearly doubled, from their first rating of 2.6 to
a rating of 4.9. For the second three weeks, the participants were given placebo.
Confidence and self-esteem both increased significantly by the end of the study: self-esteem was significantly higher after three weeks, and then remained high throughout the following three weeks on placebo. Frequency of sexual desire significantly increased by the
second week, and satisfaction with frequency and inten-sity of sexual desire continued to increase even three weeks after YTE was discontinued (switching to placebo). In addition, during this study, participants acquired new hope that their decreased level of sexual
satisfaction would return to normal again.
YTE increases sexual desire in healthy adult men.
This was a twelve-week, double-blind, multi-crossover study. The participants were thirty-one healthy Norwegian men, aged thirty-eight to sixty-five. They continuously rated their sexual desire on personal questionnaires while taking YTE. Half of the participants took
the YTE, while the other half took a placebo. Sexual desire increased significantly more in the men taking YTE than in those taking the placebo. The results of this study and others were reported in the Journal of International Medical Research (Vol. 25, No. 2, Mar/Apr 1997).
YTE increases muscle growth, strength, and performance.
Professor Törnblom conducted a six-week, double-blind placebo-controlled study at the University of Colorado and Arapahoe Community College involving thirty-two men and women ages nineteen to thirty-five. The study compared the effectiveness of two nutritional supple-ments in increasing muscle strength and muscle mass.
The effects of taking 5 grams of a 50/50 blend of YTE and creatine were compared with taking only creatine monohydrate (5 grams). Results are shown below.
In addition, a number of subjective conditions, for instance energy levels, stamina, and subjective health were also measured. Virtually all of the study participants who took YTE experienced a significant increase in physical energy, stamina, and muscle strength.
